snmanr 4 MOTOR MEANS FOR SPACE HEATER AND METHOD OF USE BACKGROUND OFTHE INVENTION This invention relates generally to a space heater, butmore particularly pertains to a novel motor-pump combination whichcompactly provides for both transfer of operation, and compactness insize, so as to improve upon related heaters disclosed in the prior art.The cfficiency in operation is essentially achieved through a rea fuelby means of the pump through the rotor of the motor and causing itscontrolled discharge through the influence of a fan blade associatedwith said rotor means.

Various types of space heaters have been available in the prior art,designed principally for providing portabilityin furnishing heat to anarea where little or no heat is available from any other source. Suchspace heaters normally include the usual motor and pump for transferringa supply of ignitable fuel through an ignition means, with a separatefan blade designed for urging the ignited fuel into a heating chamberand immediately thereafter forcing it into the area being warmed. Thereare a variety of these space heaters available upon the market, whichoperate in principle to that just previously described, and probably themore pertinent prior art is shown in US. Pat No. 2,606,014, upOn a spaceheater which turns a fan blade rotatably mounted upon a fuel conduitthrough the use of an associated motor and fan belt. While such a spaceheater is probably effective in achieving its particular purposes, itdoes necessitate the addition of an extra drive means for pumping of thefuel to achieve its passage and discharge into the combustion chamber,while a separate drive means must be employed for independentlyoperating the associated fan.

In view of the foregoing, it is the principal object of this inventionto provide a space heater incorporating a novel motor means whichsimultaneously operates both the fan means and a pump for forcingtransfer and discharge of fuel into the influence of the air currentsgenerated by said fan means.

Another object of this invention is to provide a motor-fan combinationfor use in a space heater which employs the rotor means of the motor forboth operating the fan and a pump in forcing the movement of theignitable fuel of the heater.

An additional object of this invention is the provision of a motormeans, as aforesaid, wherein the ignitable fuel travels through achannel or passageway formed axially within the rotor means of saidmotor.

- A further object of this invention is to provide an arrangement ofcontrols or valve means for regulating the degree of pressure exertedupon the ignitable fuel being discharged into the combustion chamber ofa space heater.

Another object of this invention is to provide vane members useful forcontrolling the turbulence of the air currents generated by the fanmeans operating within a space heater.

Other objects will become more apparent to those skilled in the art uponreviewing the summary of this invention, and upon a reading of thedescription of the preferred embodiment in view of the accompanyingdrawings.

SUMMARY OF THE INVENTION In accordance with this invention, generallystated, a space heater is designed to provide both efficiency in ductionin the operative components of the motor, fan, and fuel ejecting meansincorporated in such devices, with these components being used incombination with a specially constructed combustion chamber that ismounted in a manner that reduces the air turbulence, or back drafts,that are customerily encountered in heaters of this type. Thecompactness of this design is provided in operating both the fan meansand the fuel pumping and ejecting means simultaneously through the useof the accompanying motor, and more specifically, through the operationof its rotor means during energization of said motor. All of this isachieved without use of any supplementary drive means such as belts,sprockets, chain drives, or the like, but rather, both the fuel pumpingmeans'and the fan are securely fixed to the rotor means to achieve afunctioning of this invention.

The rotor means of this invention is naturally rotated through theenergization of its motor, and said rotor incorporates a channel orpassageway formed axially and integrally centrally along its length,with a nozzle or other fluid dispersing means being provided at one endof said motor to provide for a sprayed ejection of the ignitable fluidfrom the same. A fan blade is mounted directly upon the approximate endof said rotor means and provides for propelling of the ejected fluidforwardly through electrodes or other igniting means to achievecombustion of the fuel within a combustion chamber for generating thesource of heat that is driven from the space heater by means of saidfan. At the opposite end of the rotor means is provided a pump meanswhose operative components are fixed directly to said rotor, and due tothe revolving of said rotor provides the fluid pressure build up in saidpump for driving the fuel under pressure through the rotor meanspassageway for its eventual discharge, as aforesaid.

As an example of the relative capacities of the various componentsutilized in the space heater, one has been designed having a 140,000B.T.U. heating capacity which is generated from one-fourth horsepowermotor constructed having the rotor means and other components as justdescribed. Such a heater has been studied to determine that it cancirculate approximately 900 cubic feet of heated air per minute.Kerosene is utilized as the ignitable fuel, although other forms ofcombustible fuels can be utilized in this invention. It is estimatedthat a space heater incorporating the components in the way as describedcan achieve a B.T. U. rating of approximately 200,000 if a one-thirdhorsepower motor is incorporatdinto this invention, while on the otherhand, it is just as likely that a oneeighth horsepower motor couldprovide a quantity ofheat somewhere in the vicinity of 70,000 B.T.U.where the space heating requirements are of a lesser demand.

Frequently in space heaters of this type wherein a combustion chamber isarranged concentrically within an outer heating chamber, when a fanmeans is operated four urging the generated heat out of the space heaterand to achieve its circulation within the space being warmed, usuallythe rotation of the fan blade causes various turbulences. in the natureof back drafts, or draws the air in a reverse direction, quite contraryto the desired flow of the heated air out of the forward end of thespace heater. To rectify this problem, the

combustion chamber of this invention is mounted through the use of aseries of vane like members, which mount to the end of the combustionchamber proximate the motor means, and which are also fixed to theinterior surface of the heating chamber. It has been found that throughthe use of at least a pair of vanes of this nature arrangedsubstantially vertical and off center, while extending partially acrossthe open end of the combustion chamber, there is a tendency to reduceany back drafts, deplete air turbulence at this location, and to providea continuous forward thrust of the fan generated air for moving both theignitable fuel through the ignition means and then into the combustionchamber, and subsequently outwardly of the space heater.

While this invention as described herein is analyzed as being adaptedfor space heating purposes, and essentially one having enhancedportability, it is just as likely that the compactness that is designedinto the fan, pump, and motor means of this invention provides for itsapplication in other types of heaters, as for example, the built-inheaters used in mobile homes, or any other similar type pumpingapplications.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings, and referringparticularly to FIG. 1, there is shown a perspective view of the spaceheater of this invention generally designated at A, and whichincorporates a heating chamber 1 which is mounted by means of a seriesof brackets, one as shown at 2, to the upper surface of a fuel tank 3,said fuel tank having the usual intake line covered by a cap 4 providingaccess fo periodically replenishing the fuel supply, as required. In aspace heater, as previously described, incorporating a one-fourthhorsepower motor, a fuel tank having a capacity of approximately twelvegallons provides adequate fuel for sustaining the operation of a heaterfor a substantial period of time. In addition, the type of fuels thatmay be utilized in this heater may be any form of the usual fuels havingsufficient octane or combustibility rating to readily support ignition,and kerosene has proven to be an adequate ignitable fuel. To provideportability to this heater, there are provided a pair of wheels, oneshown at 5, being rotatably supported by an axle 6, with one of thesecombinations being provided on either side of the fuel tank. Inaddition, front supports 7 provide stability for the heater when restingupon the ground, as when in operation. Furthermore, a handle bar 8projects forwardly of the heater, and obviously provides convenience andfacility in the movement of this portable space heater. Verticallyspanning across the front opening of the heating chamber 1 are a seriesof braces 9, which structurally reinforce thechamber at this location,in addition to preventing any unauthorized access into the chamber,particularly when operating. There is also shown extending from the sideof the chamber 1 a utility cord 10, which provides electrical energy foroperation of both the motor and the ignition means as will behereinafter described.

By referring to FIGS. 2 through 4, various sectional views, or hiddenline outlines, of the internal components of this space heater aredisclosed. Particularly, these components are mounted substantiallywithin the heating chamber 1 of this invention. Within this heatingchamber there is provided a combustion chamber 11 which is substantiallycylindrical in shape, and is arranged approximately concentric withinthe said heating chamber. The forward portion of the chamber 1 1 isfixed to the inner surface of said heating chamber by means of a seriesof braces, as shown at 12, while the back end of said combustion chamberis fixed in place also by a series of spaced braces, as at 13. On theforward end of the combustion chamber 11 there is provided a series ofbraces 14, which connect to the end of said chamber 11, and are designedfor retaining a concave dispersing plate, as at 15, to provide properdispersing of the heat being forced out of said combustion chamber andforwardly of the space heater. To provide further control in thedischarge of the generated heat, the forward end of the combustionchamber 1 1 is provided with an additional marginal lip, as at 16, whichextends slightly across this open end of the chamber, and also has anaperture 17 provided therethrough for passage of the generated heat.

In addition to the back end of the combustion chamber 11 being braced bymeans of the brackets 13 to the inner surface of the heating chamber 1,there are also provided a series of vane like members 18 which aresecured to the lip 19 formed at this end of the chamber 11, in additionto being fixed to, or extending into proximity with, the inner surfaceof the heating chamber 1. A pair of vanes are shown in this particularstyle of space heater, and it should be noted from FIG. 2, that theupper vane 18 is arranged substantially vertical, being arrangedslightly off center of the space heater, and projecting at its lower end20 partially across the open end 21 of the combustion chamber 11. Inaddition, the lower vane like member 18 is of similar construction tothe vane member just described, also being arranged vertically andslightly off center, and having its upper end 22 projecting partiallywithin the opening 21 provided at this back side of the combustionchamber 11. To briefly expound upon and reiterate the reasoning forthese vane like members as previously described in the summary of thisinvention, it has been experienced that without these vanes 18, arrangedas shown, that as the fan means of this invention is operated, there isa tendency for air turbulence to occur at this location of thecombustion chamber, effecting a form of back draft or decrease in theefficiency of the air entrained fuel to travel forwardly into thecombustion chamber 11. As a result, to much combustion occurred just atthe nozzel end of the motor means, de-

creasing the efficiency of operation of this space heater, and causingexcessive warming of the heater components. 1

In the rearward portion of the space heater is disposed the motor means23 which, as previously described, provides the drive for operation ofthe fan means 24, mounted approximately at the forward portion of therotor means 25, while the pump means 26, providing the pressure fortransfer of the fuel, is operatively mounted to the opposite end of saidrotor. The motor means shown may comprise any form of standardelectrical motor presently available, and preferably may comprise analternating current motor that is operative from standard alternatingcurrent, although a direct motor could just as likely be utilized inthis invention. The motor is mounted to the. upward portion of the fueltank 3 by means of a pair of legs, one shown as at 27, which connect toa series of bands, as at 28, for holding the motor firmly in place, tostabilize it during its energization, and to reduce vibrations.Referring also to FIG. 5, a more detailed sketch of the motor means 23is more accurately shown and includes the usual stator 28 having therotor 25 and its armature 29 disposed for rotation therein when exposedto the usual electromotive forces. As previously described, the rotormeans 25 has a channel or passageway 30 extendin g axially and centrallyalong its length, and in this particular embodiment, said passagewayopens at both ends of said rotor. On the portion of rotor extendingforwardly of the motor means there is mounted the fan blade 24, and atthe forwardmost portion of the rotor there is disposed a nozzle means 31providing for a controlled discharge of the fuel traversing through saidrotor passageway 30. This nozzle is of the usual type, is threadedlyengaged with the end of the rotor means, ad includes a ceramic or othermaterial filter 32, and further incorporates a check valve, as at 33,designed to provide a slight pressure build up of the fuel before it isdischarged from said nozzle, with the frontal portion of the nozzlecontaining the usual core 34 which may or may not spin to provide for asprayed discharge of the pressurized fuel. It might be commented thatwhile the nozzle is shown as beng threadedly engaged to the end of therotor means 25, to dispose it axially in line with its passageway 30therethrough, it is just as likely that other forms of fluidcommunications between the rotor means into the nozzle may be achieved,as for example, by having the rotor project interiorly of the nozzle,and with the passageway 30 bifurcating approximately at the end of saidrotor, and opening laterally out of the sides of said rotor means.Hence, the passageway need not extend specifically from end to end ofthe rotor means, and need not necessarily only open axially from the endof said rotor.

Disposed intermediate the end of the nozzle 31 and the opening throughthe lip 19 of the combustion chamber 11 is an ignition means 35comprising a pair of electrodes across which a high potential is chargedto provide adequate sparking to achieve firing of the fuel emitting fromthe end of said nozzle. It can be seen that the discharge of this fuelfrom the end of the nozzle, and its immediate passage between saidelectrodes, such occurring asa result of the fuel being pressuredischarged from the end of said nozzle and being exposed to the aircurrents generated from the fan means 24,provides for almost totalentrance of the igniting fuel into the combustion chamber 11. Theseelectrodes 35 extend downwardly for mounting to either the heatingchamber 1 or on to the top of the fuel tank. Circuit lines from theelectrodes, not shown, connect with the usual transformer, which in thiscase may be mounted between the motor legs 27, with said transformerbeing energized along with the motor from the current traversing thecord 10. The transformer may be of a size to convert one hundred tenstandard voltage to approximately 10,000 volts, which develops apotential across the pair of electrodes and induces the necessary arcingto provide continuous ignition of the nozzle ejected fuel.

As further shown in FIG. 4, at the rearward end of the rotor means 25there is'provided the pump means 26 that pumps the fuel from the fueltank to the aforesaid nozzle. The pump means is confined in anintermediate pump housing 36 and a valve housing 37, both of saidhousings being rigidly secured to the back side of the motor 23. By alsoreferring to FIGS. 6 and 7, it can be seen that a series of fastenersmay project through the aligned apertures 38 provided through both saidhousings, to fasten them tightly to the back side of said motor.In'addition, the intermediate housing 36 is provided with a series ofears 39 which may also contain apertures 40 through which otherfasteners may secure for holding said housing to the motor casing. Theintermediate housing is milled to provide clearance, as at 41, to allowfor its flush mounting against the back side of the motor 23, withoutinterfering with the rotor means 25 projecting rearwardly therefrom. Thehousing 26 has an opening 42 disposed centrally therethrough to allowfor the projection of the rotor 25 therethrough, and a seal 43 providesa fluid tight relationship between these two components to prevent anyof the fuel being pumped from gaining entrance to the motor 23. The pumphousing 37 is provided with an inlet 44 which communicates by means of afuel line (not shown) with the fuel tank 3. Said inlet 44 is incommunication with an intake port 45 that exposes the fuel to the pump46, with said pump communicating with an outlet port 47 that furthercommunicates with a chamber 48. The chamber 48 is in fluid passingcommunication with the passageway 30 disposed axially within the rotormeans 25. The pump housing 37 has an opening, as at 49, which is axiallyaligned with the rotor passageway 30, with this former opening beingthreaded to receive a plug that normally maintains it in closure. But,the plug can be removed and a pressure gauge inserted as duringservicing of the pump to check its discharge pressure. And, in addition,when it is desired to clean the rotor passageway, the plug (not shown)may be removed and a brush inserted and manipulated therein. Anadditional passage 50 extends upwardly from the chamber 48, and insertedwithin this passage is a check valve 51 which is designed to providedischarge of any overflow fuel, with the passageway 50 alsocommunicating by means of another fuel line (not shown) back to the fueltank 3 for returning any excess pumped fuel. It might be remarked thatin the preferred operation of this invention, the check valve 33disposed within the nozzle 31 may be set to pass fuel that exceeds apressure of p.s.i. while the overflow check valve 51 may be set toreturn the pumped fuel to the fuel tank when it exceeds a pressure of117 p.s.i. Obviously the pressures delineated have only been determinedto work adequately in the size of space heater described in thepreferred embodiment,

and said check valves are of the adjustable type, to provdie for theirresetting and functioning at other pressures.

The pump means 46 is more accurately disposed in FIG. 7, and said pumpmay comprise a gear or screw type rotary pump that furnishes axial flowof the fluid through the passageway 30 of the rotor means 25. Thespecific type of pump disclosed in the preferred embodiment comprises agerotor type pump, having an outer gear 52 which is slidably mounted foreccentric rotation within a cut out portion provided in the face of thepump housing 37, with said outer gear having an inner gear 53 disposedfor rotating in unison with said outer gear, with said inner gear beingfixed to the rotor 25 to rotate simultaneously therewith. A key may fitwithin the slot 54 to provide this securement of the inner gear to therotor end. The arcuately shaped intake port 45 of the pump housing isshown at the downward portion of the inner and outer gears and isarranged in overlying relationship with the somewhat meshingrelationship between said pair of gears, with the arcuately shapedoutlet port 47 maintaining a similar relationship with the upwardportion of said gears. As is known in the operation of a gerotor pump,the pair of gears as they revolve through their intake cycle expand orseparate their spacing with respect to each other, in this particularinstance, the intake cycle being the turning through the lower segmentof the pump,

with said expansion between the pair of gears shown as at 55, but aseach inner gear teeth becomes horizontally disposed, as the one shown at56, the gear teeth reach a point of maximum separation for drawing infuel through the intake port 45, and during continued rotation, asthrough the upper cycle, a contraction of the space 57 forces the fuelout of said pump and into and through the outlet port 47. Hence, it canbe seen that the gerotor type pump operatively mounted to the back endof the rotor means 25 provides an effective and compact means forpumping the fuel from its tank directly into the rotor means 25 foreventual discharge from its nozzled end.

In the description of the preferred embodiment, the invention has mainlybeen analyzed as a portable space heater, but the motor means, pumpmeans, and fan relationship, being so compact in design, can just aseasily be embodied within other types of heating devices, or therelationship of a pump means to the back side of a motor for forcingsome form of a fuel or fluid through a rotor can obviously have otherapplications than in the heating field. In addition, various type ofthermostatic controls can be utilized in conjunction with the spaceheater described, so that the device may be operated automatically inresponse to the ambient temperature within the surrounding space beingwarmed. Furthermore, such a thermostat may control any type of switchmeans that may provide for a starting or stopping of the operation ofthe motor means, in addition to precharging the electrodes to providefor instant ignition of the fuel as soon as it is discharged from thenozzle. Furthermore, such a switch means may be responsive to some formof a flame out or other control that determines when the flame hasbecome extinguished, so that the heater may be shut off and the fuelsupply curtailed. These type controls are believed to be readilyavailable in the art.

Numerous variations in the construction of the pump and motor means ofthis invention, in addition to the space heater generally described,within the scope of the appended claims, may occur to those skilled inthe art in light of the foregoing disclosure.
